[Corrective osteotomy of the ankle joint].

Osteoarthritis of the ankle joint affects a younger and often occupational and sport-active patient group than hip and knee arthritis and in the majority of cases has a secondary or posttraumatic origin. Corrective osteotomy is a biological and functionally attractive option for these young and active patients with asymmetric arthritis and correctable malalignment as the native joint is preserved and subsequent arthrosis can be potentially prevented or delayed by arthrodesis. Decisive for the success are consistent 3‑dimensional diagnostics, precise planning, correct interpretation of the indications as well as completely addressing the fibular, hindfoot and instability components.
